This lamp very low quality and doesn't work, seller refuse to refund
i bought 2 lamps. first burned up after 9 days of using. everyday i watched film ca. 1,5 - 2 hours. summary it works 18 hours while the seller ensures that it works 3000 hours. then i loaded second lamp which burned up ribbon cable in my projector. this product and seller approachment is fatal misunderstanding. seller on that problem said to me that i should use original lamps.
if you like waste your money then buy it. But honestly i do not recommend this seller and his product
